Unit 7Conditionals

Conditional clauses using if

Main points

  1. You use conditional clauses to talk about a possible situation and its results.
  2. Conditional clauses can begin with if.
  3. A conditional clause needs a main clause to make a complete sentence. The conditional clause can come before or after the main clause.
  4. You use conditional clauses to talk about a situation that might possibly happen and to say what its results might be.

You use if to mention events and situations that happen often, that may happen in the future, that could have happened in the past but did not happen, or that are unlikely to happen at all.

If the light comes on, the battery is OK.

Ill call you if I need you.

If I had known. Id have told you.

If she asked me, Id help her.

  1. When you are talking about something that is generally true or happens often, you use a present or present perfect tense in the main clause and the conditional clause.

If they lose weight during an illness, they soon regain it afterwards.

If an advertisement does not tell the truth, the advertiser is committing an offence.

If the baby is crying, it is probably hungry.

If they have lost any money, they report it to me.

Warning: You do not use the present continuous in both clauses. You do not say If they are losing money, they are getting angry.

  1. When you use a conditional clause with a present or present perfect tense, you often use an imperative in the main clause.

Wake me up if youre worried.

If he has finished, ask him to leave quietly.

If you are very early, dont expect them to be ready.

  1. When you are talking about something which may possibly happen in the future, you use a present or present perfect tense in the conditional clause, and the simple future in the main clause

If you are going to America, you will need a visa.

If he has done the windows, he will want his money.

Warning: You do not normally use will in conditional clauses. You do not say If I will see you tomorrow, I will give you the book.

  1. When you are talking about something that you think is unlikely to happen, you use the past simple or past continuous in the conditional clause and would in the main clause.

If I had enough money, I would buy the car.

If he was coming, he would ring.

Warning: You do not normally use would in conditional clauses. You do not say If I would do it, I would do it like this.

  1. Were is sometimes used instead of was in the conditional clause, especially after I.

If I were as big as you, I would kill you.

If I werent so busy, I would do it for you.

You often say If I were you when you are giving someone advice.

If I were you, I would take the money.

I should keep out of Brendans way if I were you.

  1. When you are talking about something which could have happened in the past but which did not actually happen, you use the past perfect in the conditional clause. In the main clause, you use would have and a past participle.

If he had realised that, he would have run away.

I wouldnt have been so depressed if I had known how common this feeling is.

Warning: You do not use would have in the conditional clause. You do not say If I would have seen him, I would have told him.
